Data and data sources are not transparently stated, where possible, based on multiple corroborating sources |
There is a brief description about the structure of the model, its inputs, policies, etc. However, the study does not include detailed descriptions of model structure, equations, or schematic figures, nor does it explicitly link the publicly available Model Manual. |
The scenarios are well designed to address the research questions, and to assess short, medium and-long term impacts of decarbonisation policies. |
The study does not transparently analyse or present uncertainties associated with key input assumptions. While the study includes limited qualitative discussion of broader contextual uncertainties , these are not systematically linked to variations in input assumptions, nor are they reflected through uncertainty bands or alternative input pathways in the figures or tables. |
The study presents outputs transparently across key indicators. However, the linkages between specific input assumptions and quantitative outputs are not explicated. The model mechanics are referenced but not unpacked in relation to each result. |
|
Data up-to-date, with the bounds of data availability constraints |
The application of the model consistent with its design and structure. Granular sectoral demand projections and assumptions around technological changes are laid out in considerable detail. |
The study notes that internal and local experts were involved in designing and reviewing scenarios, and the broader High-level Policy Commission1 included prominent policymakers. However, it does not explicitly state that Indian government policymakers directly co-developed or validated the scenarios. |
The study does not discuss the model inputs or its causal mechanisms in detail. Additionally, the study is not reflective of the uncertainties of the modelled causal mechanisms or its consequences on the outputs. |
The study acknowledges some modelling limitations, it does not reflect these uncertainties in the conclusions or policy recommendations. |
|
Inputs justified through clear reasoning, particularly when based on projections. However, inputs not adequately reflect growing uncertainties over time. |
The model is not equipped to evaluate the social impact of decarbonisation, or the effect of specific policies and policy challenges. |
The report does not account for varying socio-economic pathways. |
The model results are presented as single-point projections extending to 2060, with no time-varying confidence intervals or formal treatment of how uncertainty compounds in the long term. |
The report does not clearly present Validation of key outputs. While the study draws on literature and notes engagement with experts, these appear primarily to inform inputs and scenario framing rather than to validate model outputs. |

6. Note: India does not reach net-zero, “due to the residual emissions from agriculture and select industrial sectors (remaining emissions in 2070 of 1.8 and 0.4 GtCO2e in the LoS and Accelerated scenarios, respectively)” .However, coal emissions will reach net zero by 2070.

Interpretation of Model Results
DEVELOPMENT PATHWAY
The study provides limited coverage of macro-structural development assumptions (e.g., urbanisation, sectoral composition, demand drivers, and electrification) and therefore offers limited insight into how development patterns may evolve beyond the policy-ambition differences captured in the scenarios.
ENERGY TRANSITION PATHWAY
The study outlines broad sectoral energy and technology shifts under net-zero scenarios but provides limited discussion of system adequacy, enabling infrastructure, and the feasibility of key technologies and demand-side measures.
EMISSIONS
The study projects emissions outcomes through a mix of forward policy simulation and net-zero-constrained pathways, but focuses primarily on CO₂ emissions and provides limited detail on sectoral sources, drivers of emissions reductions, and the feasibility of key mitigation technologies.
INVESTMENTS
The study highlights the scale and direction of investment needs under net-zero pathways, but presents deterministic estimates without uncertainty analysis or sufficient detail on timing, financing instruments, sources, or distributional impacts.
EQUITY AND RESOURCE IMPACTS
The study acknowledges aggregate employment shifts and selected resource constraints but does not systematically analyse equity, informal economy dynamics, regional or socio-economic distributional impacts, or the broader natural resource implications of large-scale technology deployment.
ENERGY SECURITY
The study links net-zero pathways to reduced fossil fuel import dependence and improved energy security, but does not assess emerging import dependencies for clean energy technologies or examine how improved energy security translates into reliable and equitable energy access.
